Think forward. Speakers complicate aerodynamics, sound proofing, and add weight where you do not want weight. Cars are just drones that don’t know how to fly yet. We’ll all want to be wrapped in the most aerodynamic space and weight conscious vehicles possible, because it’s going to be a balance between comfort, range, and economics.

Efficiency gains are great, but the bigger gains are to be had in manufacturing, installation, and overhead costs. If we’re just talking residential, companies spend a couple thousand in customer acquisition costs per installation. The utility scale stuff is MUCH cheaper per kW, but can still wring out some more savings in siting, permitting, interconnection, and overheads. Panel efficiency gains tend to help more when space is more of a concern. If you can spread out, then much cheaper, less efficient panels are often the better choice.

Flat panel speakers are nothing new. Dayton Audio (https://www.daytonaudio.com/topic/excitersbuyerguide) sell exciters you can put on any surface to make it into a loudspeaker. The sound quality highly depend on the material you put it on. As a general rule, do not expect high quality sound unless the material is optimal. There are several videos on Youtube which demonstrate them. A great one here: https://www.youtube.com/watch?v=XC814uQjlaE&t=1562s&ab_channel=AmplifyDIY

The news from LG is that they apparently have designed a new type of exciter. Do not expect miracles.
